Honda Odyssey Heating/Cooling Problems

    letmedoit,

    My 2004 Odyssey is having similar problems. Compressor turns on when A/C is turned on and blows cold for about 5 minutes. Then the compressor kicks on and off continually and doesn't produce any cooling. This A/C hasn't been charged or worked on since the last charge in 2007 because it has good pressure (30-35 psi low side pressure) while running and has cold A/C when it works. I am curious what you found to be the cause of your problem, or if anyone esle can give me any input. Thanks.

    Erick, this is silly, but it turned out to be the alternator. Apparently, the alternator was not generating any juice, so that battery was low. When it because so low, the AC shut off. Somehow, the next day, all was back to normal, until 3 days later when I got stranded on the road. I took it to a local shop, and they replace the alternator. No more problems after that.

    I guess, these new cars electrical systems are so different. It used to be on older cars, that if the battery was bad or low on juice, then all systems would go off at the same time.

    The way the symptons on this van appeared threw me off and I thought for sure that it was the AC and I was looking at a $1000 repair.

    Anyhow, good luck to you.

    I'm taking mine in for the exact same problem. Did you find a solution yet?

    it turned out it was the alternator not working, thus battery was low on power, and the AC unit shut off. I replaced the alternator, now I'm back in business.

    Hi guys, 1999 Honda Odyssey rear heating is good, but front heating quit working, it blows air but no heat, some one told me it will start working if you flush the radiator, i m not sure what should i do, i appreciate some one to help me, thanks
  • letmedoitletmedoit Member Posts: 4
    I had the AC issue come back to haunt me. Initially I thought I had fixed it by replacing the transistor assembly (located on the interior of the van), as it was suggested in several forums and on Youtube. That seemed to have fixed it for 2 months. The problem is now back.

    As in the initial problem, symptoms are that the AC will blow cold air at times only. Fan works well.

    Any ideas where else to look? I know it's not a freon leak, as AC will blow cold air when it wants to.

    Much appreciated,
    regards.

    My 2004 Odyssey has the same problem. I replaced the heater control assembly but it didn't fix the problem. Did you solve it and if so, how? Thx
  • tdetde Member Posts: 1
    well actually it blows - but bearly. I have 2007 odyssey and the heater is extremely weak - in fact the 'feet' setting there is no air circulation. Is this common fixable ...? What up?
  • ruthgreeruthgree Member Posts: 1
    Have a 2000 Honda. On New Year's Eve, there were no lights on the dash for the heating area, and no heat or defogging. Then the heat came on. Then there was a noise and we smell something that smelled as if something was burning.

    Now there's a low metallic whirr when the car starts, that gets very low as it's on. The dash lights and heater work.

    Firestone wanted to replace our A/C compressor for $1K. Said the clutch and pulley assembly on the front of the compressor "went bad", and that's why there was a grinding sound. Said the smell was the freon escaping.

    Said it would be throwing off metal pieces that might stop the power steering.

    Opinion?

    They want to do the repair with a remanufactured part.

    about 2004 Odyssey- rear heater/ac & rear sound system not working. what do you think is the problem?
  • dl6401dl6401 Member Posts: 1
    My 2000 Odyssey is not blowing cold air. When I turn the a/c on it is blowing, but not getting cold. It has been checked for freon and I have been told that there is no leak. I recently took it to Pep Boys and was told it was the compressor along with hoses,etc,etc. When I asked the guy about the fan not moving he didn't even know what I was talking about, so how do I know he's telling the truth. I know the fan doesn't move when I turn the air on and I don't want to pay$1000 to get this fixed.

    Please help!!!

    Our AC compressor died today at 77,000 miles, we just replaced the power steering pump 3,000 miles ago!
    Honda needs to "beef up" their warranty or people will start looking elsewhere!
  • jim384jim384 Member Posts: 1
    The A/C blows warm air only, and only when fan is on max. Dealer first replaced a $160 A/C "switch". Dealer said this worked 30 seconds, then failed. Dealer now says I need $540 Climate Control unit.

    I'm hugely disappointed in Honda. What is next to go wrong? I have purchased Hondas for the past 20-30 years because of their quality. I'm not sure if my next vehicle will be a Honda.

    I need to remove an air vent for the ceiling interior. One of my kids was plaing with the louvers that direct the air and unsnapped the plastic louvers from the piece they snap into. It can be put back togther if I could figure out how to remove that trim piece from the ceiling. Anyone ever do that?? Thanks
  • tim1996tim1996 Member Posts: 1
    Dealer is probably clueless... look at forum for replacing the blower motor resistor (transistor assembly) part number 79330-S84-A41... I have a 2004 Odyssey too... with the same symptoms...(The A/C blows warm air only, and only when fan is on max.)

    I bought the part at the dealer today for $75 and replaced it myself... A/C is up and running and fan works at all speeds again.

    My AC has stopped working on my 2010 Odyssey that I purchased 1 month ago. It only has 1400 miles on the car. They are diagnosing the problem but said they can tell the compressor is not engaging. Has anyone else had a problem this early on - I'm very concerned about what this holds for the future.

    My honda air conditioning had stopped working last year and this year finally we got around to taking it to the dealer. I was shocked too at the cost of replacing the compressor. I have been reading the posts and looks like it's a common problem but Honda is not acknowledging it. Should I bother calling them at all or just bite the bullet and get the repairs done ? I'm not a very confrontational person so don't want to call up the dealer or Honda CS and argue about it if there is no luck. Any help will be appreciated.
  • robr2robr2 Member Posts: 8,805
    Do you have a good relationship with the service dept - meaning are you a regular customer and give them high scores on surveys? If so, ask the service advisor to contact Honda on your behalf for a good will gesture - that you've heard there have been issues with the A/C. No need to be confrontational - just ask. The worst they will say is no.

    If you don't have that relationship - you're probably out of luck.

    Most dealerships have "silver bullets" they can use for good customers. I know I could go to my dealership with my 2000 Ody with 105K if the tranny went and they'd find a way to help me out. I do all my service there and give them high scores. They like me since I'm a profitable customer and they are willing to go the extra mile. Too many folks forget that.

    I am having similar a/c problem - but the defrost won't engage, and can't change the blower location (where the air blows out from) - none of the lights on the a/c dash work, but the fan blows at different speeds (hot air, not cooled). I am thinking maybe it's the transistor based on posts. I found this online and it may help people. http://www.youtube.com/watch?v=ByacfcUJSYA Hopefully it's okay to post the video, it's not great quality, but shows you the location of the transistor 79330-s84-A41 Honda, or JA1428 Autozone. Good luck and hopefully this works for me. :sick: I checked all fuses first, and pressure seems okay, actually a bit high. but that shouldn't affect if the a/c blows and the lights, only the compressor I would think.

    You'd be crazy to try to strike up a "good" relationship with a Honda service department. I mean would you try to strike up a good relationship with the IRS just in case you ever need their? No. When the time comes they will dig through your wallet no matter what you say about them. Just ask how much it costs to replace a cabin air filter on a >05 and after Odyssey, if its anything more than the price of one at autozone (like $10 or $20) then you're paying too much.

    I have a 2005 EX Odyssey that is having consistent A/C problems. Had a relay replaced and it ran well for 2 months and then stopped. There is no leak, ac refrigerant is well above min and below max, new filters, there is a road guard on it to protect the compressor, and fuses all check. The belts seem fine, I will take another look to make sure. The compressor seems to be engaging but no cold air, just hot. Fan is fine, loud but fine. Any thoughts? Alternator? Belts? Clutch? Transistor?

    I have a good napa shop I can take it too, once fixed my ac on an F150 for 1 hour shop labor because the clutch wasn't fully engaging. A washer did the trick. I'm sure the dealer would've replaced the entire thing for $1500. So I trust this shop but if I can try a simple fix today that'd be fantastic.

    BTW, worked for a GMC dealer for 2 years. I have my reasons for not trusting dealers. If you feel as if you can trust a dealer when you buy a car to have shown you the best price on the sticker then you can pay for the dealers maintenance I guess, otherwise, run.

    Just had my Odyssey repaired due to a stone hitting the condenser. Total cost $781.05.
    I just spoke with Honda Factory Rep, no help there. I just wish they notified me about the problem, I would have gladly paid to have the protective screen around it before the rock incident happened. My vehicle has only 27965 miles on it. I am not very pleased with Honda at this time, I have to wonder what other time bombs they are not telling anyone about. My first experience with Honda and probably my last. So much for listening to Consumer Reports.
    We have a 99 Mountaineer that has never had the A/C even topped off and you can hang meat in it on a hot Summer day.
  • jy7619jy7619 Member Posts: 1
    I have the exact same problem on our 09 Odyssey. The AC stopped working twice on two different road trips. Did you get it resolved? I'm taking my car to the dealership in a couple days for them top look at it again because they couldn't figure it out last time.
  • clvaughanclvaughan Member Posts: 1
    Much the issue here, started out with the front fan not working but rear fan does but not cold air. Now nothing works, not even the LCD display. All fuses are fine but unsure of the relays. I have noticed however that besides the AC issue that the heated seats don't work and the adjustable mirrors don't work. Related? Any suggestions would be appreciated.
  • texasbear10texasbear10 Member Posts: 3
    My Honda Odyssey 2005 has developed the following problem. We normally set the temperature control on 72 and on AUTO, and it has worked fine for 5 years for both heating and cooling. This past summer the air from the front vents started coming out warm. We had to keep turning the temp down to get cold air out the front vents. Now it has to be about 64 before we get cold air do not get warm air in the front vents. The rear vents all blow cold air. All fan speeds and other controls work properly The problem is that the front air is having warm mixed with the cold at to high a temp. So it appears that some temp sensor is not functioning properly in the front. The compressor has been checked and is fine. Any ideas will be appreciated. Thanks
  • 43434343 Member Posts: 8
    I had the exact same symptoms. I bought the part for about $40 from a Honda Dealer at Bernardiparts.com, watched the video listed in the #72 reply in this string a couple of times, swapped the new part for the old part in about 15 minutes, and voila..........it works just like new ! The biggest challenges were finding a Phillips screwdriver short enough to manuever around between the floor of the van and the transistor, and contorting myself into the right position to reach the screws. Otherwise it was a breeze.
  • moore22moore22 Member Posts: 1
    If I am not mistaken, the problem you have has a recall. I have progressive insurance and there listed with info about my van is recall information as they come up and the wireing harness has been a hot issue with these vans. I'm not that technical so I could also be incorrect, but worth a look into.
  • grdanesgrdanes Member Posts: 4
    when the temp is set at between 70.....80 the air out of the vent starts out nice and warm but then after a while cold air starts coming out of the vents which would sort of be ok if it was July and 100 degrees outside! Im wondering if anyone else is having issues like this with their 2011 TIA
  • texasbear10texasbear10 Member Posts: 3
    To: grdanes, Have you checked the temp coming out the front vents and also the rear top vents at the same time. With my temp control set on 72, and it is 90+ outside, my the front vent air temp will be warm while the back top vents will be cold. This indicates that there is a mixing of warm with cold out the front vent. My fan speeds all work properly, front & back.

    The part listed above that some have replaced will fix a fan speed problem, but apparently not a temp control problem. There is a thermister located elsewhere that is hard to get to that may be the problem I have. Your & my problem appear to be the same and different to most of the others mention in this list. :confuse:
  • grdanesgrdanes Member Posts: 4
    I'm being driven insane by this......it's 43 windows open, temp set at 75 I've got cold air blowing on me.......pos van :mad: :mad: :mad:
  • azkid2azkid2 Member Posts: 47
    Sounds like you solved that problem. This may not apply, but if an owner hasn't changed the in cabin air filter in a looooong time it can affect the performance of ac/heating, as I know it did on mine.

    As I took the vehicle in to get transmission replaced the AC went out. The front and back fans were blowing, but it was warm/hot. After paying $$$$ for transmission, went to my regular mechanic about the AC. He tested it and found it was an "electrical" issue and must see a specialist. Then the specialist took more than a week to determine the computer was going bad and must be replaced. Feeling my pain and understanding I was out $$$$ for the transmission he proposed a Plan B, which was to replace the evaporator temp sensor and rewiring AC to engage when ignition was on and bypassing the faulty circuit. After $$$ paid the AC now starts about two seconds after I turn it on, but the front fan works only at full blast and will not automatically adjust to cabin temperature....

    Now two weeks later the front blow fan does not work at all, but cold air "seeps" slowly from the front vents. The back fan is fine. Specialist took a look and figured the fan motor was deteriorating. Tapping and wiggling it hard caused it to blow harder, but now it won't even respond to that. Specialist recommended replacing the unit, which I have done (thanx AutoZone)...but the new unit still will not engage. Suggestions?
  • dawson46dawson46 Member Posts: 2
    I am having the same issues with my wifes 2008 Odyssey. AC randomly stops. Sometimes if we open all the windows and doors - it will again blow cold. Sometimes it will blow cold by starting and stopping; other times it works after turning the heat on for 1-2 minutes.

    Also, the defroster will not clear the windows. this is becoming a safety issue. :mad: :lemon:
  • phx70phx70 Member Posts: 3
    What ended up fixing the blowing hot problem? I've replaced my transistor assembly 2 times without fixing the problem. I need to turn mt temperature control down to 64 before I get cold air. If turn it up past that, it immediately blows hot air.
  • texasbear10texasbear10 Member Posts: 3
    Update: I have not solved the problem. I just adjust the temp to get either hot or cold out of the front as needed. Usually in hot weather, I sent it at 68 or below to get cold. One like suggested it might be either:
    Part # 39794-S0K-A01 RELAY ASSY., POWER (4P) (MICRO ISO) (OMRON), or
    Part # 80560-S0X-A01 THERMISTOR, AIR CONDITIONER.
    A diagram and pictures can be found at (If you put in your Honda Information):
    http://www.hondaautomotiveparts.com/auto/jsp/mws/prddisplay.jsp?inputstate=5&cat- cgry1=ODYSSEY&catcgry2=2003&catcgry3=5DR+EXL+%28LEATHER+RES%29&catcgry4=KA5AT&ca- tcgry5=A%2FC+COOLING+UNIT

    The relay appears to control the fan, and not be this problem. So it may be the Thermistor? :confuse:
  • phx70phx70 Member Posts: 3
    Thanks for responding. The problem I was having was warm air would blow out of the dash, even with the temperature control off unless I lowered the temperature to 60 degrees. The recirculation light would then come on and finally blow cold. Unfortunately, it was either too hot or too cold. I did resolve the problem. It ended up being a disconnected diverter lever that connects to the air mix motor. The air mix motor is under the dash on the passenger side and to the left. Almost behind the center of the dash. It has a green wire connector attached to it. With the ignition key turned to the on position, I verfied the air mix motor was functioning while turning the temperature knob on the dash back and forth. I noticed a white plastic lever with a long slot in it behind the motor moving, but not moving much. I could manually move it much farther by hand. When I did this I could hear a door opening and closing. I moved the plastic lever all the way the other direction and managed to get it slid over a guide pin attached to the air mix motor. I see the guide pin is suppose to fit in the slot in the lever. After re-attaching, the air works as it should. Not too hot or too cold. I hope this helps anyone else experiencing the same symptoms.

    Hi folks,
    My front heater and AC are not working. Don't want to spend an arm and a leg if there is something I can do on my own. I see many had this issue on different models. It's cold in winter and would be nice to have the front heater. I am overworking my rear heater (as it works) to heat the car before stepping into the car :-( Please help! Thanks much in advace and a Happy New Year!

    -Duke
  • phx70phx70 Member Posts: 3
    If your fan is not blowing, you will not feel any A.C. Or little heat. If your fan motor will not work on AUTO, but will turn on when maxing out the fan knob, it is most likely the transistor assembly. The part number is listed in these forums. If that is not the case, there are some fuses and relays located in the engine compartment...good luck!
  • duke47duke47 Member Posts: 3
    Thanks Phx70 - the fan works fine and it blows pretty much outside air at that temperature. When I crank up the temperature, it does not heat up, when I lower it all the way to 60 (in auto mode) it does not kick in the AC. Would appreciate a link to any info.
    -Duke
  • duke47duke47 Member Posts: 3
    update here - I took the plunge to change the transistor/resistor - cost was $70 and change. Unfortunately it did not appear to fix the issue. I checked out the resistor and transistor on the old one - they seem fine. The cap seems OK as well. So, I am stuck again without heater. Could someone help. BTW, the video in this discussion was extremely helpful to change the transistor/resistor. Trick I used, instead of the screw driver, you can also use a 9/16 hex nut which is much easier than the screwdriver. Anyway, look forward to hearing to some advise. Again, the fan blows fine, but both AC and heater is gone - could it be the thermostat? (also, dealer quote to change the resistor - $149 and he would not budge; I did it in under 35 minutes).

    About a month ago my 2007 Odyssey suddenly release large amount of freeon while I was driving. The whole fogged up and I first thought it was smoke due to overheat. After pulling off the road and let down the window and shut off the engine. When I started the car again, it didn't happen again. I called Honda Corporate to report the problem and they told me to take it to the dealer which I did. Sadly, they dealer told me that they couldn't duplicate the problem and sent me home, but the service adviser did say that she has seen it happened to another car before. When I searched this problem online, I found out many odysseys have the same problem and mine is not the only one. Just two days ago, while driving on the freeway with a full van of food, the air conditioning suddenly shut down - even the fan. After seeing so many odyssey having the same problem, I called corporate again to find out whether there's a recall. They actually told me that there is no recall for this problem and I just need to take it to the dealer and pay for the repair myself.
    I began to think Honda is ripping its customers off by selling detective products. My Odyssey has not only air conditioning problem, but also transmission, steering pump and brake problem. My Odyssey is the most expensive and has most problems vehicle that I have ever own.

    I posted about my problem earlier. After finding I needed to replace the transmission, my AC stopped blowing. The AC turned out to be a symptom of a computer problem. After paying big bucks for new transmission I was faced with having to replace the computer for more big money. To save $$$ the computer shop did a Plan B for me and rerouted around faulty circuit to allow AC to blow (full blast only). 24 hrs later the fan went out... Time for a new vehicle!!!

    Must be either a creature of habit or like to subject myself to more hardship, but I actually like the Odyssey when it works...so bought the 2011. At the dealership looking at their warranty, the sales rep warned about "ghosts in the machine" that should be tackled when first evident. Reminded me how the old van for months had issues like rear windows not responding, sliding doors opening on their own, the back light for the odometer not working... little things that I could deal with. Letting these things go without attention could perhaps result in the larger problems I faced later. Lesson learned for me. :sick:

Get rid of the van ASAP......February 2012 Motor Trend Long Test Article 2011 Odyssey Touring Elite, 6 months old, 14999 miles "...we'll have the technicians look at the transmission as well. Over time, shifting has become rough, and occasionally upon acceleration between first and second gears, the transmission seems to be shuddering."

    Hi, I'm having the same issue. Could you please tell us how the problem was resolved for you?
  • ktnrktnr Member Posts: 255
    According to discountacparts.com:
    "Your compressor failed for a reason. The number 1 reason is contamination in the system. Cleaning out this contamination is crucial to ensuring that the new compressor is not also contaminated. Always flush and evacuate before changing parts. Always use A/C system flush solvent. If it is not perfectly clean after the flush and vacuum, we recommend re-flushing the system."

    My Atlanta Honda dealer botched my A/C system repair by initially just installing a new compressor and running the system to note poor performance. Only then did they inspect the accumulator/drier (replacement of this part is REQUIRED by every compressor manufacturer as part of the warranty) and noted it was leaking desiccant balls and other black junk into the system. THEN they decided to flush only the evaporator line and replace the clogged dryer and also the contaminated condensor (the A/C radiator at the front of the car, often difficult to flush). This is noted right on my invoice! The invoice doesn't mention cleaning or replacing the expansion valve nor purging the other line - things any half-trained A/C technician would have done. Obviously, my new compressor now has it's oil flooded with seven years of accumulated black crud. So I just paid $2,000 for a brand new compressor which WILL fail prematurely.

    I have a case open with Honda corporate to see what they can do given that the repair ddn't follow the Honda's - or anyone's - service procedures. You have to watch your dealer closely to ensure they perform the A/C repair correctly. The warranty on the repair will be only 90-days labor / 12 -months parts so, if the new compressor fails again within a year, you get to hassle with them all over again on the labor. After a year, you're just out another $1,500-$1,800.

    Honda responded to my complaint about my A/C system repair. I had faxed them Denso’s warranty on their compressors (requires system purging and dryer replacement or the warranty is immediately void) along with industry articles describing the importance of thoroughly cleaning A/C systems to avoid contaminating a new compressor. I faxed them a copy of the Honda Service Bulletin showing the easy and very inexpensive alternative to the dealer’s suggested $480 power steering pump rebuild to cure a minor noise issue. I explained how the Service Advisor switched from protesting AGAINST additional work that would be wise (but would have required him to come in on his day off OR split his commission with someone else) to pushing unnecessary and over-priced work the next day (once he was resigned to protecting his commission by coming in on his day off, the Service Advisor wanted to make it damned worth his while). I explained how the dealer tried to charge me 8.976111 shop hours (a plugged number they made up) before they backed off their “mistake” and cut the labor charge by 40%.

    Bottom line: Honda said repairing a contaminated A/C system just by replacing one part at a time was “proper”. The attempted over-charges and commission wrangling are solely between me and the dealership. Honda suggested I contact the dealership Service Manager again to see if he can explain what they had previously refused to explain. In a word, Honda offered me NOTHING.

    If you’re looking for Honda dealer service in downtown Atlanta, you’d be wise to go far North (Woodstock, Georgia) or far South (Morrow, Georgia) instead. Even then, ask in advance to insure that your Service Advisor will be working the next day too in case your car needs to stay overnight. If anyone quotes you a price over the phone, get their full name to avoid hassles over service prices and commissions. Better yet, find a small, local shop who works off their reputation and repeat customers instead.

    I have a 2004 Honda Odyssey where the A/C compressor is staying running even though dash button says A/C Off ... I have pulled the pressure switch wire off .. says running only time it turns off is if I remove the Fuse or A/C compressor Relay ... anyone know what might be causing the problem ... I know the Dash part could be part of the problem but I hear the PCM/ECM has a relay built into it .. if someone knows of a known issue I could use some info so I don't spend money on parts I don't need
